WebEx outage history

Webex users in Europe and Africa faced an outage starting at 3:22 AM UTC as Webex Meetings and Webex Calling services entered a degraded state. Some users could not start or join meetings, and calling services were disrupted. Webex Contact Center users also reported failed calls and login issues, indicating a regional service disruption that affected collaboration across the region.

Engineering investigations led to mitigation steps and ongoing monitoring. The status progressed toward restoration, and by 9:02 AM UTC the core Webex Meetings and Webex Contact Center capabilities were restored, with monitoring continuing to confirm stability. The outage lasted several hours and was confined to the Europe and Africa region, with no broad global impact reported.

WebEx Meetings and WebEx Recording entered emergency maintenance at the WebEx Japan data center beginning at 10:02 AM UTC. During this window, access to these components was temporarily affected while the maintenance was in progress. The maintenance was isolated to the Japan data center and did not indicate a regional-wide outage. The window concluded and the affected components returned to service at 3:02 PM UTC as WebEx Meetings / WebEx Recording moved from maintenance back to up.

Webex Calling underwent multiple maintenance windows starting at 12:02 PM UTC, with Webex Calling / Provisioning moved into maintenance. A subsequent Emergency Service Maintenance window began on 12:32 AM UTC and a standard maintenance window followed at 3:32 AM UTC, keeping the component in maintenance through the period. The service was restored when the Provisioning component came back up at 8:02 AM UTC. This sequence indicates extended maintenance across Aug 13-14 with restoration on the morning of Aug 14.

Impact surfaced around 5:52 PM UTC, as Webex Calling provisioning for new Wholesale sites and Webex for BroadWorks customers began to fail, while existing sites remained unaffected. Engineers identified the root cause and completed remediation by 6:12 PM UTC, with services restored and monitoring ongoing. A maintenance window began at 6:32 PM UTC to confirm ongoing stability, extending into the next day.

The disruption was global in scope but primarily affected onboarding workflows for Wholesale and BroadWorks customers. Onboarding operations were impacted for most of the afternoon on 5:52 PM UTC through the maintenance window, and provisioning returned to normal by 9:02 AM UTC. Existing deployments continued to operate, and Webex communicated remediation steps and monitoring status.

Webex users relying on BroadWorks experienced provisioning problems that blocked new site and order creation, with some disruption to inbound call notifications on the Webex mobile app. Impact began at 12:02 PM UTC as maintenance and DNS changes were rolled out (DNS propagation can take 24–48 hours). By 5:52 PM UTC, Engineering identified a global provisioning issue affecting Wholesale and Webex for BroadWorks, while existing sites remained unaffected. Remediation progressed and provisioning services were restored by 6:12 PM UTC; operations then moved back into monitoring, with full provisioning returning to normal by 9:02 AM UTC during the ongoing maintenance window.

WebEx users relying on BroadWorks and the Webex App for mobile experienced missing incoming call notifications during a scheduled maintenance window for Webex Calling / Provisioning. Inbound push notifications did not reach mobile devices, while outbound calls and calls answered on desktop or desk phones remained unaffected. The issue began during maintenance at 3:02 AM UTC and progressed through multiple updates as engineers investigated the push notification service. Status checks at 6:32 AM UTC, 7:12 AM UTC, and 7:58 AM UTC tracked progress toward restoration.

Webex Calling / Provisioning entered a scheduled maintenance window that began at 12:02 PM UTC and concluded at 2:02 AM UTC. During the window, the Webex Calling / Provisioning component was listed as under maintenance, with provisioning-related features potentially affected. The maintenance lasted about fourteen hours before the service returned to normal.

WebEx Calling provisioning entered a scheduled maintenance window beginning at 5:02 PM UTC and concluding at 3:32 AM UTC. During this period, provisioning-related operations for WebEx Calling were placed in maintenance, which may have temporarily limited tasks such as adding users or updating provisioning configurations. The WebEx status page indicated the maintenance was in progress and then that services returned to normal after the window closed, with the overall window lasting about ten and a half hours before full functionality was restored.

Admins managing Webex Calling reported failures when adding or deleting devices through Webex Control Hub or APIs. The issue affected administrators globally across Commercial and Webex for Government, primarily impacting devices added by MAC address; devices provisioned with activation codes continued to function. The disruption complicated provisioning and inventory updates for IT teams and could slow deployment of new devices or changes to existing configurations.

Impact began at 3:47 AM UTC and engineers moved to restore service with remediation steps. Remediation was completed by 8:07 AM UTC, and the affected Webex Calling / Devices component returned to healthy operation by 10:02 AM UTC. The service has since remained stable and is being monitored to ensure ongoing reliability.

Users of WebEx Calling in the US region experienced one-way audio or complete loss of media for PSTN calls. Impact began at 3:02 PM UTC as engineering started investigating and the Webex Calling / Calling, Media and Services components were affected.
